Borosilicate Glass Lens Acrylic Round Disc Acrylic Round Disc

Product DescriptionGlass Discs with Good Thermal and Optical Properties

Glass discs, whose material can be soda-lime, borosilicate or quartz, have different sizes and applications. The difference of soda-lime, borosilicate and quartz is the different content of silicon dioxide. The more silicon dioxide contain, the glass disc is stronger in thermal and optical properties.
The diameter of our glass disc can be 5 mm to 1000 mm. The thickness can be 0.3 mm to 40 mm. Compared with other factory products, our glass discs surface is polished and no bubble and edge is exact round and polished. What's more, Our glass discs can work in very high temperature as well as acid and alkali environment. In addition, as optical glass, our glass discs light transmittance can reach 93%.
With good thermal, mechanical and optical properties, the glass discs are widely used in instruments, LED lights, optical industry and so on.

Features and Advantages:
Corrosion resistance
The glass disc especially quartz can resist acid and alkali. The quartz do not react with any acid, except hydrofluoric acid.
High working temperature
The soda-lime glass discs can work under 450 °C high temperature and the quartz glass discs can even work under 1200 °C for a long time.
High light transmittance
The quartz transmittance can reach 95%.
Polished surface
There is no bubble or scratch and the surface is flat, clear and polished.
Perfect edging handling
The edge is exactly round. It can be ground and polished. The polished edge is more smooth.
ApplicationAs cover discs, they can protect from dust and moisture.Glass discs are used in optical industry because of it's high transmittance.As cover glass and slides, glass discs are widely used in instruments.It is used in LED lights because of its good optical properties.
